National Weather Service Issues Heat Advisory for Bay Area and Central Coast
The National Weather Service announced a heat advisory for the Bay Area and Central Coast, effective from 10 a.m. Wednesday to 10 p.m. Thursday. Temperatures are projected to reach 10 to 20 degrees above normal for this time of year, with peak heat expected on Wednesday. Inland areas are forecast to experience the most significant warming, with some locations reaching the upper 90s and low 100s. Cities such as Concord, Livermore, and Cloverdale are expected to see highs in the mid-90s to low 100s. Coastal regions will remain cooler, with temperatures ranging from the mid-70s to low 90s. The warming trend is driven by a ridge of high pressure building over Northern California, combined with residual tropical moisture from Hurricane Marie. This atmospheric pattern will disrupt the cooling sea breeze, allowing temperatures to rise rapidly inland. Residents are advised to stay hydrated and take extra precautions during the hottest parts of the day. A beach hazard warning remains in effect through Monday evening, warning of sneaker waves and strong rip currents with breaking waves up to 10 feet high.
